The foramen ovale (FO) is located in the middle cranial fossa and found anteromedial to the foramen spinosum. The FO transmits numerous anatomical structures such as the mandibular branch of the trigeminal nerve (V3), the accessory middle meningeal artery, and the lesser petrosal nerve. The FO is clinically important, particularly with regard to surgical procedures that cannulate the foramen. Such procedures include transovale treatment of trigeminal neuralgia and biopsy of parasellar lesions. The morphology of the right and left FO of 84 adult skulls were compared. The maximum diameter, area, and perimeter of the right FO were significantly larger than those of the left FO. Knowledge of the asymmetry between the right and left sided FO is important in preventing improper cannulation and subsequent intracranial hemorrhage. Research was supported by funding from the WV Research Challenge Fund [HEPC.dsr.14.13].
